' MANGLE.

Specification of Letters Patent.

Application filed January 4, 1921. Serial No. 434,953.

r I To all whom it may concern on which Be it known that I, JAMES NORRIE a oiti-.

zen of the United States, residing at Quincy, county of Norfolk, Commonwealth of Massachusetts, have invented a certain new and useful improvement in Mangles, of which the following is a. specification, reference being had therein to the accompanying drawings.

The invention relates to a new and use-.

ful improvement in mangles for use in iron ing flat goods, such for instance as sheets, pillow cases, towels, etc. In devices of this character which have heretofore been made, there have been sometimes provided an apron the article to be ironed is fed between two rolls. In some such devices the article with the apron is drawn through to the opposite side where it is taken out, or sometimes the rolls have been reversed in rotation and the article is brought back again to the front side of the machine but the outer end of the apron has hung loose. In others an endless feed apron is employed and the article iscarried by the feed apron around between the two rolls and back again onto the same side from which the article is fed. By still another method the article is wound up with the apron around one of the rolls in the ironing or mangling process,-

and then drawn out again by reversing the direction of rotation of the rolls. In this last type of machine the end of the feed apron on the operativeor feed side of themachine elther hangs down free or rests free on a table and has no takeup for the apron on the reverse moveme'nt. One object of the present invention is to provide two rolls for the opposite ends of the apron, one of said rolls being a feed roll from which the apron is fed to carry the article between the two mangle rolls and to wind the apron and article around one of the mangling rolls, and when the machine is reversed and the apron is unrolled and the article is drawn back from between the inangling rolls, the said apron is automatically re-wound around the feed roll.

It has also been found that when only a single apron is employed that the article being mangledis liable to become slightly twisted or crinkled due to its not being fed straight and becomes creased or wrinkled during the operation. One object of the present invention is to provide means whereby the article is kept from wrinkling during relates to its passage through the mangle rolls. This feature of the invention consists of providmg a second apron which is fed in such a manner'as to meet the carrier apron in superposed position thereon where they pass between the mangling rolls, so that the article to be ironed will lie between an upper and a lower apron, and as both of the aprons are positively fed the article lying between them will be kept from wrinkling.

Another feature of the invention relates to the pressure rolls and the mountings for the same.

the driving mechanism and the mountings therefor.

The invention will be fully understood from the following description when takenin connection with the accompanying drawings, and the novel features thereof will be pointed out andclearly defined in the claims at the close of this specification.

In the drawings, F ignre 1 is a front elevation of the machine embodying the invention. 1

Fig. 2 is a side elevation of the machine shown in Fig. 1.

' Fig. 3 is a. section on line 3-3 of Fig. 2.

Fig. 4 is a detail view of the winding spring connected with the takeup roll for the supplementary apron.

Referring'now to the drawings, 1 and 2 represent the two side members of the frame in which the several rollers are mounted, said side members being tied together by a cross tie 3 at the top, able means. A feed apron 4 is wound around a core roll 5 which is provided with trunnions 6 journaled in vertically slidable bearings in the side members of the frame, as shownin the drawings; that is, the bearings consist of boxes 7, one at each" end of the roll, each of which is slidably mounted ingroov'ed ways in the side of the frame and Patented July 26 1921..

or by any other suit-.

Another feature of the invention The said apron 4 runs from the feed roll 5 V around over a guide roll 10 jo-urnaled at the outer end of the shelf 11, thence follows on the upper surface of the shelf around onto a takeup roll 12 which is provided with trunnions l3 journaled in vertically slidable bearings 14. Said bearings 14 are slidable;

in vertical grooves 15 in the side members l-2 of the frame of the machine.

A friction roll 16 1s interposed between upon the periphery of the takeup roll 12,

inverted U-shape 0r jecting from outside winding'of the apron 4 on the rolls 5 and 12, being held in such engagement by the upward pressure of the springs 8 against the vertically movable boxes 7 in which the roll 5 is journaled.

A presser roll 19. is provided with trunnions. 20. which are journaled in boxes 21 which are vertically slidable insaid slot 15,

the periphery of said presser roll resting when the apron is wound around the roll 12, said roll 19 will press upon the outer winding of the apron on said roll 12,1as shown in Fig. 2.

The boxes 21 in which the roll 19 is journaled, are provided witha grooved neck portion 22 which lies between the side of the frame and the end of the roll 19, thus spac ing the, end of the rollsomewhat from side frame. The boxes 7 in which the roll 5 is journaled are also provided with a neck portion 23, having side grooves 24, and the presser roll 16 is formed with a neck 25 having flattened sides 26 in vertical alinement with the grooves 24 and 22 respectively of therolls 12 and 19. A yoke 27 of somewhat hairpinshaped, and preferably made of stiff wire or of a small iron rod, goes over the top of thevneck 22 of the box bearing for the upper roll and the legs of said yoke, extend down in the grooves of said neck, thence in the grooves of the neck 23 of the takeup roll 12, thence down along the flat sides of the neck of the lower presser roll 16, and preferably down below also the lower takeup roll 5. The lower ends of the legs of said yoke are tied together by a crosshead 28. An suitable means for connecting the lower ms of said yoke with the crosshead 28 may be employed, the means shown being to u rovide the lower ends of the said legs wit screw threads and to provide clamp nuts 29 on said legs onthe upper side of said crosshead, and nuts 30 on the lower side of said crosshead so that the said cross head may be securely connected with the legs-of said yoke. The said nuts will prevent the crosshead from movement, either up or down, on the yoke. V

A spring 31 is secured to said crosshead 28 between the legs of the yoke, the lower end of said spring being made fast to a stationary portion of the frame in any suitable way. As shown in the drawings the lower end of the spring passesthrough an ear 32 prothe frame, and has a screwthreaded nut on which is screwed a nut 33 on the under side of said ear 32, and the the upper end of the spring passes through the crosshead and is clamped by nuts 34-35 to secure it in the same manner that the legs of the yoke are secured to said crosshead. Said spring is under tension and tends to pull the crosshead and the yoke downward, thus holding the upper end of the yoke by an elastic. pressure firmly down against the neck 22 of the bearing of the upper r011. 19..

This in turn exerts a downward elastic pres- 7 sure upon the takeup roll 12 or upon the outer winding of the apron 4 on said roll. Inasmuch as said roll 12 is mounted in vertically slidable bearings, the pressure is also transmitted to the friction roll 16. As the o said friction roll 16 has a rigid bottom stop.

by reason of its trunnions 17 being seated in the bottom of the groove 18 at the lower endof the slot 15 in Whichthe two upper rolls are mounted, there is alwaysa friction between the three upper rolls 19, 12 and 16. The lower roll 5 also has'an upward elastic pressure against the friction roll 16by-reason of the upward pressure of the spring 8. An apron 3.6 is made fast at one end to a tubular shaft 37 andv is wound around said shaft 3,7, the other end ofsaid apron being made fast to the roll 12 and being adapted to wind around; the same. The two'aprons, 36 and 4, both meet and become super-imposed upon each other where they pass be tween the two rolls 16 and 12. The article which is to be mangled will be fed. onto the surface of the apron 4 where the apron passes over the shelf 11 and will be carried by the apron: 4 into the throat or passageway between the two rolls 12, 16. The two aprons together with the article embraced between them will bewound up aroundthe rel-112. r V v A coiled spring 38 is inclosed within the tubular sleeve 37, Fig. 4, oneend of said spring being made fast at 39 to a; rod 40 which passes through said sleeve, the; other end of said sprin being made-fast torthe 110 sleeve 37 at 41. he said rod 40'is formed with a square head 42 which is engagedin a square socket in the bracket 43 of said sleeve, so that the rod will be kept from rov tating while the sleeve 37 rotates something- 115 after the manner of a springsha'de' roller, but the I construction differs somewhatfrom a spring shade roller, as will be later explained. Said spring has its coils arranged in such manner that when the apron 3.6 120 being wound up around the roll 12, the said spring will be wound up to greater tension. The ordinary spring shade roller is provided with a ratchetand pawl to prevent backward rotation of the shade'roller, ex- 125 cept when the pawl is released. In this device there is no ratchet {and pawl prosaid sleeve or roller. It is normally prevented from yielding to this, however, by the friction created by the downward pressure of the takeup roll 12 due to the pull of the spring 31 on the yoke 27.. When, however, the takeup roll 12 is positively rotated backward, as will be hereinafter described, this will unwind the apron, 36 from the roll 12, and the spring roller 37 will take up the slack and re-wind the apron 36 on the sleeve or spring roller 37 as fast as it is released from the takeup roll 12.

Means are rovided for manually rotating the roll 12. igidly connected with the box 14 of the roll 12 is a bracket 44 which extends horizontally on the outer side of the side frame 1, and the outer end of the trunnion 13 projects beyond the outer face of the box 14, and is journaled in said bracket 44. The bracket 44 is vertically slidable with said roll 12, being slidable onthe outer face of the side member 1 of the frame. A spur gear 45 is mounted fast on the outer end of said trunnion 13, and the pinion 46 is mounted on a stud 47 projecting from said bracket 44. Said pinion 46 engages with said spur gear 45. A crank 48 is connected with said stud shaft 47, whereby the said pinion 46 may be manually rotated thereby rotating the spur gear 45. By reason of the gear 45 being mounted on the shaft or trun-J nion 13 which carries the roll 12, said roll 12 will be rotated. When theroll 12 is retated, the upper roll 19 will also be rotated through the friction between the said roll 19 and the surface of the apron wound around the roll 12. The friction of the roll 16 and the apron on the roll 12 also causes the roll 16 to rotate, and in like manner the friction between the roll 16 and the apron on the lower roll 5 causes roll 5 to rotate. As the aprons are unwound from the rolls 5 and 12, the several rolls will still be maintained in frictional engagement with each other by the springs 8 and 31.
